Although HTTP's simplicity is its greatest strength it is also its main drawback. As a result, the HyperText Transfer Protocol - Next Generation (HTTP-NG) project has emerged as an attempt to replace HTTP. HTTP-NG promises to deliver a much higher performance and additional features to support efficient commercial applications in addition to simplifying HTTP's security and authentication features. Some of HTTP-NG's goals have already been implemented in HTTP/1.1, which incorporates performance, security and other feature improvements to its original version HTTP/1.0.
A basic HTTP request involves the following steps:
There are two versions of HTTP, version HTTP/1.0 and the latest version HTTP/1.1. The change made in the revision was mainly in the connection for each request and response transaction.
